My big pet peeve is AWS adding buttons in the UI to make "folders".
It is also a fiction! There are no folders in S3.
> When you create a folder in Amazon S3, S3 creates a 0-byte object with a key that's set to the folder name that you provided. For example, if you create a folder named photos in your bucket, the Amazon S3 console creates a 0-byte object with the key photos/. The console creates this object to support the idea of folders.
